MacBook pro - keeps running when sleeping/lid shut

[UTH]

Very often when I head into town and have shut my laptop I can feel that it remains warm in my bag and by the time I get to the office I've lost most of the battery life.
I've started telling it to 'sleep' before shutting the lid but that doesn't seem to make a difference.

It doesn't happen every single time which is what really baffles me. I'm fairly sure everything is up to date, and I've restarted it a few times in case that might help, but this intermittent problem is still there.

Any ideas? I'm hoping it might be a way to get work to get me a new one, but I'd happily take a fix for this one!

Will be worth making a note of what apps are running when the laptop goes into sleep mode

You may have one that isn't sleeping very well.

I've even taken to shutting most of them, so I'm just left with Chrome (quite a few tabs open admittedly) calendar, Slack and Excel and that's about it.
Ideally I'd have Zoom, powerpoint left running too, but I do shut them down a lot of the time.

I'd put money on Slack being the culprit

May be an outside chance but have you checked for fluff in the HDMI port if it has one? My thinking is that my laptop stays awake if the lid is closed and a monitor is still plugged in as it thinks it's active driving a monitor. Maybe there's something in there grounding a pin or something.

Nope, doesn't have one

Ok, I'll make a point of shutting slack the next few times and see if that helps

I had this with a user who used to use Slack, restarting the app each day resolved the issue, I am scraping my memory but there is a service that wont sleep once slack has been open for a while.

Hasn’t chrome recently become problematic for some users?

Ok good to know, easy to just close slack at the end of the day, so hopefully that'll be the fix.

Only if you don't have much ram (sat here on my windows machine and its currently consuming 3.6GB or RAM)

Do you have a mouse or other Bluetooth peripheral with you?

There is a setting to allow the Mac to wake if you move a mouse/etc.

Might seem a ridiculous suggestion - but why not turn it off for the journey?

Yep, I guess that is also an option. Just got so used to shutting lid and it being fine. No biggie to turn off I guess.

I did try to test overnight if closing slack helps, came down to find Mrs UTH had plugged it in before we went to bed haha. Doing me a favour that actually didn't help!

Try going to Activity Monitor, then energy, and see if anything is listed as preventing sleep.

Sounds like an Intel Mac. Every Windows laptop I’ve had has done this as has every Intel Mac I’ve had.

My M1 Macbook Pro never does this.

The solution is to buy an Apple Silicon Mac!

I've never had a problem with Intel CPUs and sleep generally.

My MBP M3 Pro is great but this isn't an Intel issue this is something preventing a machine from sleeping

I suspect you have the last of the intel pros.

They were appalling for it, the fans used to run and they even drained the battery when turned off. Get really hot.

When the new M1 came out the case was bigger and they never run the fans and don’t do this ridiculous draining whilst shutter off.

My Mac Air , last intel, is the same. Drains the batter when off in the cupboard and gets crazy hot.

Love my latest Pro never gets stressed. Probably the the 96GB ram
